🥇Cold supply chain in China

When it comes to operating a cold storage warehouse, the issue is to maintain the right cold storage temperature for the product inside while keeping personnel and equipment warm enough to perform well and function at optimal capacity. Refrigerated and frozen food accounts for the majority of the product being stored in cold storage facilities but it is also important to other industries such including pharmaceuticals for example. Given that the need for cold storage keeps on growing, we are, at SINO Shipping, able to adapt to all your needs when it comes to controlling temperature of your products during the storage and the transports thanks to our flexibility.


General information about Cold Chain Management and our services

What is the cold supply chain?

*It consists in how you distribute goods in a particular controlled temperature, including the transport and the storage. 

In case of international supply chains, there are different possible transport conditions, which secure the good protection of the cargo. The cold chain concerns the transport of food, pharmaceutical, or chemical products. Indeed, these products have to be stored and transported in strictly specified ranges of temperature.

Cold chain management and logistics use temperature’s control transportation and storage to ensure the product remains within its recommended conditions.

What we offer at SINO Shipping – Our services

At SINO Shipping, the services we offer when it comes to cold supply chain in order to facilitate the shipping of your goods are the following:

  • Ensure the handling conditions are maintained throughout the cold chain.
  • Ensure the appropriate storage conditions throughout the cold chain.
  • Maintain the product safety and integrity throughout the cold chain during all the shipping.

The cold chain infrastructure gathers suppliers, transport system, warehouses, and the end customers.

When it comes to the transport system, we can ship your goods by airplanes, boats and trains thanks to different options such as refrigerated trucks, refrigerated railway wagons and refrigerated cargo containers.

The fresh cargo has introduced a low-cost solution that protects fresh perishable products and is sensitive to transit temperature, while ensuring a lower overall cost for shipping.

Cold Chain Logistics Planning Planning is the key to successful and efficient Cold Chain Distribution. Yet even with careful planning, many companies still miss out on opportunities to save money, streamline processes and increase overall efficiency. This could be related to packaging, staying current with the latest technology for monitoring temperature or choosing an experienced transportation provider – all of which can have a significant impact on efficiency.

Unproven Packaging Systems

When dealing with Cold Chain shipments, companies should always use packaging that has been properly tested or qualified for maintaining the required temperature range. As an example, it may not be appropriate to use a packaging system qualified for transporting shipments under dry ice conditions for a commodity that needs to be kept at refrigerated temperatures. We have come across situations where shippers added cold packs to an insulated design assuming that it will keep the shipment cold, but it’s a gamble if the system has not been tested under these conditions. The system simply may not be designed to hold at this temperature. The bottom line is: if the package hasn’t been tested to perform under very specific conditions – the shipper is open to a great deal of risk.

Monitoring Temperature

Regardless of the packaging system chosen, companies should also always employ some sort of temperature monitoring device. Advancements in device monitoring technology have given shippers a variety of options that range in cost.

Cost Versus Value

Conversely, some shippers may be using packaging configurations that are too sophisticated and usually too costly for their needs. It’s not cost effective, for instance, to use a packaging system that will maintain temperature for 72 or 96 hours for shipments that are likely to be delivered within 24 hours. Likewise, using a large active shipping configuration when a passive system is sufficient can also result in unnecessary costs, including paying for a lot of empty payload space if the unit’s capacity is not maximized. While some businesses have determined that it’s simpler to have a single packaging configuration for all their global shipments, many would benefit from conducting a thorough cost/value analysis.

Establishing Contingencies

Even with the best systems and monitoring technology in place, an unplanned delay or rerouting could potentially jeopardize the stability of a shipment. That’s why it’s critical for shippers to work with their transportation partners to develop contingency plans that clearly map out what is to be done in the event of a delay. This includes whether to keep packaging cold or frozen in refrigerated rooms or freezers, or replenishing the pack out as needed. These contingencies must also include the recipients of the shipment, determining if after hours delivery is an option and if proper personnel are on site to accept an after hours delivery. Keeping the lines of communication open will ultimately help avoid losses.

Active and Passive Shipping

Configurations Compared

As a first step in selecting the most appropriate packaging, it’s important to identify whether a passive or active shipping system is needed.

Efficient Cold Chain Distribution


Determining whether an active or passive system is the best solution is based on several factors including temperature, volume and destinations. Here is what you should consider when choosing a packaging system:

1.Does the product need to be frozen, refrigerated or at a controlled room temperature?

2.What is the required temperature range? Can product be out of this range for any period of time?

3.What temperature will the package be exposed to during transit based on its final destination? As an example, is the product shipping from the US to Australia where climates may be opposite at various times of the year?

4.Are different types of systems needed for summer versus winter pack outs, or is one universal configuration sufficient for year round shipping? a. If separate systems, at what temperature is it necessary to switch from winter to summer pack out and vice versa?

Volume of Product

1.What are the typical payload requirements? How much space is needed?

2.How much product is being sent? Is it a uniform number of units to each locale or will volumes vary?

3.How much is being sent? Is it a uniform number of units to each locale or will the volume vary by destination?

Transit Times

1.Are destinations all or primarily domestic (24 hour delivery)?

2.Are they mostly going to international locations (48 to 96 hours delivery)?

3. Is it a mix of domestic and global destinations? For international destinations, it’s important to factor in the amount of time needed to clear customs, in addition to transit times.

Monitoring Temperature

Advances in technology have made monitoring temperature easier and more accurate. With an array of available devices – from those that give an alert when the temperature falls outside of its range to others that provide actual, real time readings – as well as a range of price points, it’s difficult to know which to choose.

Types of Temperature Monitoring Devices

USB-Enabled: Data is gathered by a drive that is connected to a USB port in the temperature monitoring device. Upon delivery it is removed from the device and connected to a computer’s USB port. The results can then be emailed to the shipper immediately in a PDF format if necessary. Direct Information Download: For enhanced security, other devices must be retrieved and sent back to the shipper either by the recipient or the transportation partner. Once received, the information is downloaded directly from the device.

Other Considerations

1.How long can the device record? Will it withstand the length of the trip?

2.When should it begin recording?

3.At what intervals should it record? Essentially, the device should conform to the specific pack out. And like pack outs themselves, monitoring devices must be used based on the manufacturer’s specification. This includes paying careful attention to where the device is positioned. If it is placed up against a frozen gel pack, for instance, it could potentially send false readings. It is recommended to use these devices as a redundancy even when working with active packing systems that provide temperature data.

The best transportation specialists will also have strong relationships with airlines that have expertise in cold chain services. These airlines have established SOPs and handling procedures and usually offer custom facilities such as cold rooms and freezers at airports. They typically have specific density and loading procedures for cold chain shipments, and give preferred cargo positioning on the aircraft itself.

For instance, shipments are not positioned near a cargo door where they might be exposed to significant temperature variations. Pilots are notified as to what is on board, and may even have the ability to regulate temperature in cargo areas from the cockpit. Ground crew is trained to handle these special shipments as well, further expediting movement and ensuring packages or active units are not kept on the tarmac and exposed to the elements.

To Test or Not to Test

Once the packing configuration itself has been determined, it’s advisable to conduct a series of dry runs to ensure the systems work. Although pre-qualified passive designs are tested in a lab environment, which are typically fairly accurate, live transit testing is always a wise investment – especially if you have a commodity that is rare or very expensive to manufacture.

The actual testing can be fairly simple. Use a temperature device and ship some water at a refrigerated or frozen temperature to a variety of challenging locations to determine if the system is robust enough to perform under the logistics and environmental conditions in which it will be used. A typical testing scenario might consider a packaging system with a 72-hour transit life. If tests to various destinations indicate that performance starts to degrade around the 65-hour or 66-hour mark, it may be prudent to move up to a system that provides a 96-hour life to reduce or even eliminate the margin of error.

Working with a Transportation Specialist

While some companies may prefer to handle the investigation and final determination as to which packing systems are best, not all have the resources to dig as deeply as is necessary. Thus, others opt to work directly with a cold chain transportation specialist from the outset. Partnering with a third-party expert gives shippers access to a much deeper knowledge base since experts in the field have been exposed to a wide variety of “real life” shipping scenarios using various packaging configurations, both active and passive. Their knowledge and experience can help quickly identify the best configuration available in the market for your specific needs.

Planning and communication becomes critical when a transportation partner enters the equation, especially when it comes to the actual movement of packages. While evaluating cold chain transportation specialists, consider the following attributes:

• Works with shippers to pick up packages closer to flight departure times

• Knows in advance what the import/export and customs processes/ required permits are at each point of entry

• Has an established communication protocol to alert shippers of delays and determine whether consignee can place shipment in the proper environment after business hours

• Determines after hours and weekend delivery protocols, as appropriate

• Provides door-to-door or customs broker services

• Advises on expected transit, customs clearance, recovery and delivery times by country

Put your cold chain distribution strategies into action

Getting a specialist involved early in the process can help to minimize the time a product is contained in the packaging system. Internal considerations, as well as information that will be important to share with a transportation partner includes:

• What is being shipped?

• How much (size and weight)?

• How frequently?

• What time of year?

• To where?

• What are the lane segments?

• Pick up ready times?

• What is the transit time?

• What other time constraints exist?

• What is the necessary temperature range?

• At what temperature does viability of the product degrade? What is the stability data?

• What external temperatures need to be considered?

• Active or passive shipping configurations?

• Temperature monitoring employed?

• What are the per country regulatory requirements for imports? How does this impact time in customs?


Remember, since delays can happen for any reason – weather, mechanical issues, unexpected customs holdups and more – it’s important to have a clearly detailed SOP in place. Should the transportation partner open the box and replenish coolant in the event that temperature is compromised, or refrigerate the package if the delay extends beyond the system’s time constraints?

The cold or refrigeration chain is the set of logistical and domestic operations (transport, handling, storage) aimed at maintaining food or pharmaceutical products at a given temperature in order to preserve their safety and taste qualities.
If the cold chain is broken, food thaws and then re-freezes, allowing bacteria to grow. The ingestion of these bacteria can then lead to food poisoning, the effects of which vary according to the fragility of the individual, and can lead to diarrhoea, fever, or even death in the most extreme cases.
The refrigerated truck is specially designed to produce and preserve perishable goods, such as frozen food, meat, fish, milk, pharmaceuticals, chemicals, fruit and vegetables. Refrigerated sea transport of products is carried out either by conventional reefer vessels or by containers. Air transport is a means, indeed a logistical quality, which makes it possible to satisfy a need for which it ensures conditions in terms of time and quality.
The function of the refrigerated warehouse is to receive goods in order to store them for a determined time. The activity of the warehouse is essentially limited to handling operations. There are two main functions in cold storage warehouses: forklift drivers and order pickers.
Traditional warehouse: It is equipped with pallet racks (mobile or not) or stackable self-supporting containers. Mezzanine warehouse: It is used for storage and order preparation. Single level warehouse (platform): With a cold room and a large number of loading/unloading bays. High-rise cold warehouse: This type of warehouse with a storage height of over 12 m requires a stacker crane, which is generally automated.
